 That's a great search brought to you by DigiKey and Adafruit. Thank you DigiKey for making this happen every single week. Lady, to use the power of engineering help you. Yes, you find the things that you need on digikey.com. Searching for parts is an art. It's a skill. It's a thing. Lady, what are you looking for this week? Okay, so one thing I did this week is I've been trying to get some of these boards that have like very discontinued, unavailable part shortage things on there. And the feather sensor is one of the ones that was really challenging because they had so many sensors on it and all the more from different companies and they were all unavailable. But a lot of them came back into availability recently. I wanted to get this design back into the shop. And so the part that was, you know, on the great search, we actually covered like getting the list 3MDL, getting a replacement, and so other components and crystals and new pixels. The part that I want to try to replace today is this one. So this was the LSM 6DS33, which is a IMU. It's a triple oxytocelarometer gyroscope. And this is obsolete and no longer manufactured. And they recommend, digikey recommends a alternative, but you know, it's always good to like search on your own just in case if there's something you want that's a little bit different. So sorry, I was zoomed in so much. Absolutely totally unavailable. So the only thing with the gyroxylorometer is like I know just because if you go to LSM 6DS33, I used to stock it. So let's look at the discontinued ones. All right, discontinued. So this was a 16G, 2 to 16G and 125 to 2000 DPS, I scored to your SPI. I only really used I scored to be honest. And then like, you know, double tap, tap detection free fall. But it's very basic to be honest. It's a very basic IMU because the feather sands and the clue wasn't meant to be like a commercial drone or, you know, VR helmet type thing. It was like, I just kind of wanted to do some basic sensing of location. So one of the very inexpensive sensor. So like I said, we searched for nine DoF IMU replacements and nine Tomter replacements. The suggestion here is the LSM 6DSO, but let's see. There might be other options. So what we want is, well, let's just go to IMU and we'll just search because maybe we don't want ST. So let's go to stacking. Okay, so we're going to look for active. Important. I'm going to do that again. And then I want surface mounts. I'm just going to skip over chassis mount. Normally stocking, which already cuts out because again, so many chips were discontinued. And then what do I want? Biometric pressure sensor? No, but that's kind of nuts that they have that built in accelerometer and gyroscope. I don't want with a magnetometer. That's a nine DoF. I want a six DoF accelerometer gyroscope. Whether that temperature, I don't want a magnetometer. I wanted to have I squared C and SPI. Some have I three C as well. Good for them. Looks like we've got 31 options. Okay. So Bosch STTDK worth. Like totally what we expected. So there is a bunch of that, you know, that one that they suggested the LSM 6DSO TSR. And so I was like, well, let's just swap by price. And there's a couple of options. What's nice is that the prices are like reasonable again. Having seen for like a while there, it was like $100 for like a six DoF sensors kind of nuts. They're back down to two bucks. So the question is, which do I want? So I'm, you know, I'll say honestly, in this particular case, because I'm replacing the existing component and the component is the LSM 6DS family, I'm going to go with that same family. If I was starting over with a new design, I might be like, hey, you know what, let's change and go with the Bosch sensor. But I'm a little bit like I'm already doing enough work. I want to replace it with something that's the same family. So I picked ST to pick only the ST components. So now the only thing is I'm a little like actually was like, wait, there's the 6DSM TR, TR means tape and rail. So you can actually come back and ignore the TR part. There's the LSM 6DSM DSL DSO DSR DSO 32 DSV for very nice micrometer. I don't know. And then I was kind of like, there's way too many of these. I need help to know. And then the DSR X. So I, you know, I stored these by price. So in general, it's probably going to be lower quality or higher quality. But and what is nice is I'll say, you know, I'm going to get it just, I've already done this research, they're all pin compatible. They all use the exact same pin out. Thankfully ST picked, they picked this like two by three, like rectangular shape. And they put the pins always in the same locations. They did that after the DS33. So all of these are going to be pin compatible. So, you know, I could swap between them, but I really, I want to pick one if I can. So, you know, I was kind of Googling to try to figure out what the, what the deal is. I'll be honest, a little, little unclear. Some of them are a little, you know, they, they explain like, okay, this one is designed for camera stabilization. Not that it matters. So let's go to, I'll show you how I kind of like figured out what's up. So you go to the inertial module, which is just the entire family. And this is on the ST.com website. And then there's like a bazillion pop-ups. And then product selector, I'm going to shrink this down. Okay. Product selector. And then what I did is I was like, well, I know that the angular rate I wanted to have was, you know, to 2000. Because remember that was the, at the bottom here, I only need up to 2000. You're going to pay for more and more. So I don't want it to be more than 2000. And the accelerometer, I don't want it to be more than 16. And so I think this filtered it. So now I only have 12 options. And you do see like DSM, DSO, DSL. So then I kind of look into the table. I was like, well, what's, I don't think toast. There is some power mode changes. But the real thing that you're going to spend, and I'll tell you another thing, you can't, you can't sort by price here. What you can do is sort by noise density. And that's actually going to be the same as the price. Because the thing that is what makes these accelerometer drives expensive. First off, accelerometers cost like nothing. Accelerometers are very inexpensive for the most part. This has been figured out, you know, MEMS accelerometers. Not that they're, there's some that are a little bit better. They might have better filtering, but the technology is kind of well established. And the quality is kind of well established. Derascopes, what you're going to deal with is, is noisiness and drift. Because that's the thing that's going to introduce the most error into your calculations when you're doing like nine doff, you know, attitude calculations or absolute orientation calculations. And so the higher the noise density, like the more you're going to see like wiggle and drift as things like start kind of moving when they should be moving even when they're still. And you can tell, and I know, I know, for example, for a fact that the DS3TR is the least expensive of all these, not surprising, it's going to have the highest noise density. And then the lower, you know, the ISM series, we stock this one. It's a very, very nice accelerometer gyro. It's going to be lower. It's like, you know, significantly lower. It's like 30% less than the DS3TR. And then from then on, it's like the DSL is next and the M is next. So, you know, although they're very similar, they only go down by like five each one, the DSO and the DSOX, which we stock, they're kind of nice down at 70. But you start paying much, much more like the price increase, even though it goes down only by five micro G for square root hertz. It is going to be, it's going to be significantly more expensive. And so I want to get the 3TR, the DSL or the SM. And then if you go back down here, you see, yes, the SM and the SL are basically the same price. The SM is actually a little bit less expensive. And that's actually kind of nice because it also is a little bit higher quality. If you see here, it's 75 instead of 80. But otherwise, it's the same power and the same current consumption. So I think the end, which they have 40,000 stock, is the winner or is it the nice one? About two bucks in quantity. The board doesn't need to be redesigned to handle this new 2x3 pinout. But here's the good news. On the off chance that the M is suddenly unavailable, I can swap to the L. It's a firmware change only. And then, you know, maybe you don't promise more than the L model performance. And then they get the M, then it's higher quality and a little less expensive. So this is my pick for the great search. That's a great search.
